These cables are intended for use as horizontal cables, backbone cables, or in the manufacture of patch cords. Depending upon the application and system requirements, this standard provides choices for materials and flammability ratings. Additionally, the document covers minimum performance requirements for cables up to four pairs, with transmission characteristics specified up to 250 MHz for Category 6 cables and up to 500 MHz for Category 6A cables.

These Category cables are intended for voice, text, data, video and image transmission, and low voltage power supply (POE & POE+).
The cables are categorized by electrical transmission characteristics based on existing system requirements and projected application needs determined by IEEE 802.3.

The cables included are intended to conform to the cabling system architecture and design as specified in ANSI/TIA/568-C.2. Applicable definitions, test methods, and performance requirements are included.
The material, mechanical, and physical characteristics for these cables are covered under UL 444/CSA 22.2 No. 214.
